SYRINGE.

SPECIFICATION forming part of Letters Patent No. 273,373, dated March 6,1883.

Application filed October 23, 1882. (No model.)

To all whom it may concern:

Be it; known that I, RHODES LooKwooD, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in Syringes, ofwhich the, following description, in connection with the accompanyingdrawings, is a specitication, like letters on the drawings representinglike parts.

To maintain a syringe of the class herein shown in working order, thesyringe, after it has been used, should be held by the suction-pipe, sothat the bulb hangs below it, and then the bulb should be compressedseveral times, and the syringe should then be hung up with itssuction-pipe uppermost. Vhen the syringe is hung up by its suction end,both the outlet and inlet valves will drop away from the valveseat andallow the liquid to gradually tlow from it, and I[he syringe will not bespoiled so quickly, even it' the bulb is not compressed, as stated,after using. Up to the present time the syringe has n ot been providedwith any permanent attachment by which to hangit up but for such purposeit has been customary to tie a loop of s tring` about the suction end ofthe syringe, the said loop being slipped over a nail or other suitablepin.

My invention consists in providing the snction end ofthe syringe with apermanent loop or eye, thus forming a suspending device, by means ofwhich the syringe may be suspended from its suction end, so as to permitthe inlet and outlet valves to drop from their seats, the said loop oreye being preferably ofmetal, and preferably forming a part of thesuction-tube, the hook or eye being adapted to be readily caughty over anail or hook driven into the wall.

Figure l represents a syringe embodying my invention as it will appearwhen suspended from a nail, the nail beingv shown lin dotted lines; Fig.2, an enlarged detail of the foot of the suction-pipedetached, and Figs.3 and 4 modifications to be referred to. v

The injection-pipe a, its end piece, a', the bulb b, and suction-pipe,and the inlet and outlet valves (not shown) are and may be as usual.

In Figs. l and 2, the foot d of the suctionpipe is cut away at one sideto form a suspending device, shown as a hook or eye, e, to enable thesyringe to be suspended from a nail, as atf. It' desired, the hook oreye may be shaped as shown in Fig. 2, and, if desired, the

point ol' the hook might be carried down to and connected with lthe mainpart ofthe foot, as shown in dotted lines, thus making a complete eyesufficiently large to pass over the head of an ordinary nail, suoli aneye being in purpose and operation an equivalent ofthe hook.

The hook or eye might be Iliade to project from one side of the foot, asin Fig. 4. Where a loop of soft material-such as stringis em Witnesses:
